Each book is an experiment. Big time on the author's side, small time on each reader's side. There it is, the work; for you to decide whether you invest your precious time and money. Will it be worthwhile? WIIFM?

Well, if you already have made up your mind, read no further. Go get the real thing - Linchpin - in your bookstore, on-line, from a true friend, your library and so on. Or leave it for later, or ignore it forever. Up to you.
